Support-free mounting method for cantilever triangular plane truss structure
The invention discloses an unsupported installation method for a cantilever triangular plane truss structure. The unsupported installation method comprises the following steps that S1, an independent umbrella-shaped column is vertically installed at a design position; s2, main truss butt joint pieces are welded to the tops of the short columns; s3, a limiting stiffening baffle is welded to the top of the independent umbrella-shaped column, and the limiting stiffening baffle corresponds to an upper chord butt-joint square pipe used for installing the oblique main truss up and down; s4, the two sets of forward main trusses in the opposite side directions are synchronously and symmetrically hoisted in sequence through a truck crane, and after the forward main trusses are hoisted, the forward main trusses are preliminarily limited and then welded and fixed; and S5, the two sets of inclined main trusses in the opposite side directions are sequentially, synchronously and symmetrically hoisted through a truck crane, after the inclined main trusses are hoisted, the inclined main trusses are preliminarily limited, then welding and fixing are conducted, and the method has the advantages that the construction cost is greatly saved, the installation period is shortened, the installation efficiency is high, the manufacturing cost is low, and the installation steps are reasonable.
本发明公开了一种悬挑三角平面桁架结构无支撑安装方法，包括以下步骤：步骤S1、先在设计位置竖直安装独立伞状柱；步骤S2、将主桁架对接件焊接在短柱的顶部；步骤S3、在独立伞状柱的顶部焊接限位加劲挡板，且限位加劲挡板与用于安装斜向主桁架的上弦杆对接方管上下对应；步骤S4、采用汽车吊依次将相对侧方向的两组正向主桁架同步对称吊装，并在正向主桁架起吊后，进行正向主桁架初步限位，然后焊接固定；步骤S5、采用汽车吊依次将相对侧方向的两组斜向主桁架同步对称吊装，并在斜向主桁架起吊后，进行斜向主桁架初步限位，然后焊接固定，具有大幅节省施工成本、缩短安装周期、安装效率高、造价成本低、安装步骤合理等优点。
